New issue 184 by h.a.syed: C++ Strange Memory Warning Under Visual Studio 2008 SP1 on Windows 7
http://code.google.com/p/protobuf/issues/detail?id=184 What steps will reproduce the problem? 1. Compile a protobuf object in an application under a visual studio debug build. 2. Call "SerializeAsString()" on a protobuf class. 3. This may cause a memory leak warning in "AppendPartialToString" after the "string_as_array" function has returned. What is the expected output? What do you see instead? Visual studio crashed with a buffer under-run message. The stack frame which was fine before the call is now filled with garbage. Strangely though, the problem dissapears when a "Release" build is tried. My code is part of a portable project, so I tried debug and normal builds under Linux. I also ran valgrind on the binary and no leaks were reported. I am assuming this has something to do with a combination of the debug STL library provided by microsoft and the suspicious looking callto "stl_util- inl.h:85". The code is accessing the underlying string buffer via the following snippet "return s5tr->empty() ? NULL : &*str->begin();". I hope you can reproduce the issue. I am hoping the Release build is indeed free of errors. -- You received this message because you are listed in the owner or CC fields of this issue, or because you starred this issue.
